Intel's Core i7-3770K is a great CPU offering high performance at a very resonable power consumption. But this processor will cost you 47.6 percent more than the Core i5-3570K. Yes, the Core i7-3770K gives you HyperThreading, additional 100 MHz and two more MB of L3-Cache. But it doesn't give you 47.6 percent more performance and this makes - in our humble opinion - the Core i5-3570K the true star of the Ivy Bridge family. And we've got benchmarks to prove it.
